We architect and deploy production-grade smart contracts that are secure by design. Our development process is built on Solidity 0.8+ with OpenZeppelin libraries, ensuring robust, upgradeable, and gas-optimized code from day one.
Mobile Sanctions Screening Tool
Custom Smart Contract Development
Secure, audited smart contracts tailored to your exact business logic, built on industry-standard frameworks.
- Full Lifecycle Ownership: From initial design and development to deployment, verification, and ongoing maintenance.
- Multi-Chain Expertise: Deployments on Ethereum, Polygon, Arbitrum, Base, and other EVM-compatible L2s.
- Security-First Approach: All contracts undergo rigorous internal audits and are prepared for third-party review.
We deliver contracts you can trust, reducing audit cycles and mitigating the risk of costly exploits before mainnet launch.
Typical deliverables include custom ERC-20/721/1155 tokens, staking & vesting systems, multi-signature wallets, and complex DeFi protocol logic, enabling a 2-4 week MVP timeline for most projects.
Core Capabilities of Our Screening SDK
Embed a robust sanctions and AML screening engine directly into your mobile application. Our SDK is purpose-built for FinTechs and crypto platforms to manage risk, ensure regulatory adherence, and protect your brand.
Real-Time Transaction Screening
Screen wallet addresses and counterparty data against global sanctions lists (OFAC, UN, EU) in real-time. Integrates directly into your payment flow to block high-risk transactions before they settle.
Comprehensive Risk Scoring
Receive detailed risk scores for every screened entity, powered by on-chain and off-chain data analysis. Go beyond simple list matching to identify complex risk patterns and PEPs (Politically Exposed Persons).
Seamless Mobile Integration
Lightweight, native SDKs for iOS and Android with minimal performance impact. Full offline mode support and automatic list updates ensure compliance even with intermittent connectivity.
Audit-Ready Compliance Logging
Automatically generate immutable, timestamped logs for every screening event. Our system provides the detailed audit trail required by regulators like FinCEN and the FCA for simplified reporting.
Custom Rule Engine
Configure custom screening rules and thresholds tailored to your risk appetite and jurisdictional requirements. Dynamically adjust policies for different user tiers or transaction types without SDK updates.
Enterprise Security & SOC 2
Built with bank-grade security. Our infrastructure is SOC 2 Type II certified, with end-to-end encryption, zero data retention policies for PII, and regular third-party penetration testing.
Business Outcomes: Beyond Basic Compliance
Our Mobile Sanctions Screening Tool delivers more than just regulatory checkboxes. It provides a robust foundation for secure, scalable growth, turning compliance into a competitive edge.
Accelerated Onboarding & Revenue
Reduce user verification time from days to seconds with automated, real-time screening. Launch new markets faster and capture revenue opportunities without compliance bottlenecks.
Reduced Operational Risk & Cost
Minimize false positives and manual review workloads by up to 70% with our AI-enhanced logic. Lower operational overhead and protect your business from costly fines and reputational damage.
Enhanced Trust & User Experience
Provide a seamless, non-intrusive compliance check that respects user privacy. Build greater trust with your user base while maintaining a frictionless onboarding flow.
Future-Proof Compliance Framework
Our platform dynamically updates with global sanctions lists and regulatory changes. Ensure ongoing compliance without costly internal system overhauls or development sprints.
Actionable Compliance Intelligence
Gain deep insights into user demographics and risk patterns with detailed audit trails and reporting. Make data-driven decisions to refine your risk models and product strategy.
Enterprise-Grade Security & Uptime
Deploy with confidence. Our infrastructure is built on SOC 2 principles, featuring end-to-end encryption, redundant systems, and guaranteed availability for mission-critical operations.

Our Delivery Process: From Integration to Live Screening
A structured, transparent process designed for technical teams. We deliver a fully operational sanctions screening tool integrated into your mobile app, with clear milestones and guaranteed SLAs.
Discovery & API Integration
We analyze your mobile app architecture and user flows. Our team provides SDKs and REST APIs for seamless integration, supporting Flutter, React Native, and native iOS/Android.
Risk Rule Configuration
Tailor screening logic to your compliance needs. Configure watchlist sources (OFAC, UN, EU), risk thresholds, and alert triggers specific to your user base and geography.
Staging Environment Testing
Deploy and test the complete screening workflow in a sandbox environment. Validate transaction monitoring, false positive rates, and data privacy controls before go-live.
Security Audit & Sign-off
Undergo a final security review covering data encryption in transit/at rest, secure credential storage, and penetration testing. Receive audit report for your compliance team.
Production Deployment
We manage the go-live process, including certificate pinning, load balancer configuration, and monitoring setup. Achieve full production readiness with zero downtime.
Ongoing Monitoring & Support
Get 24/7 monitoring of screening performance and alert queues. Includes monthly compliance reports, watchlist updates, and dedicated technical support.
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that form the foundation of your protocol. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and comprehensive audit cycles to ensure your core logic is robust and resilient.
